	From Paul Koning <pkoning@equallogic.com>:
	* breakpoint.c (free_valchain): New function.
	(insert_bp_location, delete_breakpoint): Use free_valchain.
	(remove_breakpoint): Do not remove the valchain.
	(bpstat_stop_status): If not stopped by watchpoint, skip
	watchpoints when generating stop status list.
	* infrun.c (handle_inferior_event): Make
	stepped_after_stopped_by_watchpoint a global variable.
	* remote.c (remote_stopped_data_address): Return watch data
	address rather than zero if stepped_after_stopped_by_watchpoint is
	set.
